1- The trip to Mars didn't come out of nowhere as you think, if you remember (Chapter Two), I mentioned the fact that James' mother said she wanted his weapon to be buried with her, his trip to Mars was made to honor his mother's last wish.
2- The parameters of Survival World don't allow you to tell other people about the worlds you've visited, it's basic information that everyone knows.
3-Back at Survival World you'll keep all the injuries you've suffered.
4-Abilities such as Nen are rare among travellers, but this does not prevent them all from possessing a genetic ability from the moment one of their stats reaches ten.
5-James has never killed a human being in his life, HXH man face is not taken in count.
6-Only an increase in the sense statistic causes nausea and dizziness, it would take a large sudden increase in the other stats to cause the same effect.
7-The story will not follow a classic plot with a romance between a hero and a heroine as you thought in V4.
8-The MC won't have a thousand capabilities, I prefer to make a Mc with some capabilities that can create other capabilities as they evolve.
9-Humans aren't the only ones with access to Survival World.
10- If a stats reaches ten you will be obliged to participate in a test that will give you the opportunity to evolve towards a creature ☆☆, the stats that increases to ten will have a great influence on your innate genetic capacity.
